<p>They consist in providing to the classical spiral (4) four helicoidal grooves (8) for the stubs (6) of the cup (5) carrier of the cosmetic stick, maintaining two of these helicoidal grooves (8) their upper end (11) closed, as a conventional case, while the other two have their corresponding ends (12) opened, and at the same time that the longitudinal grooves (7) of the barrel (2) of the base body (1), have their upper end (10) also opened, all of it in such a way that in normal conditions of the case use the stubs (6) of the cups move in the couple of grooves (8) of the spiral with their ends (11) closed, by which such cup (5), and consequently the cosmetic stick associated thereof, have a limited run between the emergency and retraction end positions, while with the forcing of the rotating relative movement between the spiral (4) and the base body (1), the stubs (6) pass to the second set of helicoidal grooves of the spiral (4), the ones of the upper end (12) opened, by which the cup (5) is independent from the rest of the case, for its substitution by another spare piece, carrier of a new cosmetic stick. <IMAGE></p> |
